Description

Technical Field

[0001] The utility model relates to the technical field of transfer paper production, in particular to a transfer film coating machine. Background Art

[0002] A transfer film coater is a device used to transfer coatings, inks or other liquid materials to a substrate through a transfer film. Due to its advantages such as stable and reliable printing quality and high production efficiency, it is widely used in packaging, printing, electronics, textile and other industries to produce various coated products. The production of transfer paper is to transfer the pattern of the transfer film to the transfer paper through a coater.

[0003] The existing transfer film coating machines need to go through operations such as hot pressing transfer, cooling and curing when producing transfer paper. When cooling and curing the transfer paper, the transfer paper is usually transported to the cooling mechanism through a conveying mechanism, and the transfer paper is cooled by the fan in the cooling mechanism. However, since the position of the fan is fixed, and transfer paper of different widths is produced according to needs during production, the wind generated by the fixed fan is difficult to completely cover the transfer paper, resulting in the coating in some areas of the transfer paper not being completely cooled and cured.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 8 In an embodiment of the utility model, a transfer film coating machine includes a workbench 1, a coating mechanism 2 is arranged at one end of the top surface of the workbench 1, two sets of symmetrical tensioning mechanisms 3 are arranged on the top surface of the workbench 1, a drying mechanism 4 is arranged on the top surface of the workbench 1 and located between the two tensioning mechanisms 3, a cooling mechanism 5 is arranged on the top surface of the workbench 1 and located between the drying mechanism 4 and the tensioning mechanisms 3 that are far away from each other, the cooling mechanism 5 includes a mold frame 51, a moving component 52 is arranged inside the mold frame 51, and the moving component 5 2 is provided with a rotating assembly 53, a limiting assembly 54 is provided on the top surface of the moving assembly 52, and a fixed block 511 is fixedly connected to both ends of the opposite side of the inner side of the shaped frame 51. The moving assembly 52 includes two reciprocating screws 521 rotating between two fixed blocks 511 symmetrically arranged and located at opposite positions, and a moving plate 522 is screwed and connected between the two reciprocating screws 521. Through holes are penetrated at both ends of the top surface of the moving plate 522, and a fan 523 slides between the two opposite side surfaces in the through hole.

[0027] Specifically, firstly, the transfer film and the transfer paper are passed through the coating mechanism 2, the two tensioning mechanisms 3, the drying mechanism 4 and the cooling mechanism 5, and then the appropriate spacing between the two fans 523 is adjusted according to the width of the transfer paper, and then by starting the coating mechanism 2, the drying mechanism 4 and the two tensioning mechanisms 3, the coating mechanism 2 can transfer the pattern on the transfer film to the transfer paper, and then by starting the two tensioning mechanisms 3, the transfer film and the transfer paper can be transported. When the transfer paper is transported to the inside of the drying mechanism 4, the heat released in the drying mechanism 4 can heat the transfer paper. The solvent or water in the coating on the transfer paper evaporates. When the dried transfer paper moves into the mold frame 51, the two fans 523 are started to cool and solidify the transfer paper. At the same time, the rotation of the two reciprocating screws 521 can make the movable plate 522 drive the two fans 523 to move back and forth in the mold frame 51, and the two fans 523 are reciprocated and tilted in the through holes at corresponding positions (similar to the shaking function of a fan), so that the pattern in the transfer paper can be cooled without dead angles, making the cooling efficiency of the transfer paper pattern faster.

[0028] Embodiment 1

[0029] like Figure 4-6 As shown, in the present embodiment, one end of the reciprocating screw rod 521 passes through the side of the fixed block 511 at the corresponding position and is fixedly connected to a pulley 5211, and the two pulleys 5211 are driven by a belt, one end of the outer wall of one of the reciprocating screw rods 521 is fixedly connected to a spur gear 1 5212, one side of the mold frame 51 is fixedly connected to a motor 524, and the output end of the motor 524 is fixedly connected to a spur gear 2 5241 meshing with the spur gear 1 5212, and a rectangular groove 5221 is provided on the opposite side of the through hole, and a limiting block 525 is slidably connected inside the rectangular groove 5221, and a connecting block 5231 is fixedly connected to the top surface of the fan 523, and a round rod rotatably connected between the two limiting blocks 525 at relative positions and passing through and fixed to the connecting block 5231 at the corresponding position.

[0030] In this embodiment, the two reciprocating screws 521 can be rotated by the drive of the motor 524, and the two rotating reciprocating screws 521 can make the movable plate 522 reciprocate in the mold frame 51 (the moving speed of the movable plate 522 must be greater than the conveying speed of the transfer paper), so that the pattern on the transfer paper can have sufficient time to cool, and the situation of insufficient cooling of the coating can be prevented. The fan 523 can interact between the two rectangular grooves 5221 at the corresponding positions, and the spacing between the two fans 523 can be adjusted according to the width of the transfer paper. At the same time, the fan 523 is made to reciprocate and rotate along the axis of the round rod at the corresponding position, so that the wind generated by the two fans 523 can cover the transfer paper, so that the pattern on the transfer paper can be quickly cooled (although the wind generated by the fan 523 will be dispersed by the transfer paper and diffused around when it blows onto the transfer paper, but if the fan 523 is fixed and the transfer paper is relatively wide, the wind diffused around will become smaller and smaller, making it difficult to cool the pattern on the transfer paper).

[0031] Embodiment 2

[0032] like Figure 4 and Figure 8 As shown, in this embodiment, a rectangular hole 5222 is formed at a position corresponding to the rectangular groove 5221 on the top surface of the movable plate 522 and communicates with the interior of the rectangular groove 5221 at a corresponding position, a plurality of latch teeth 5251 are fixed at equal intervals at a position corresponding to the rectangular hole 5222 on the top surface of the limit block 525, and the limit assembly 54 includes a fixed plate 541, a fixed rod 542 is fixedly connected at a position corresponding to the rectangular hole 5222 on the bottom surface of the fixed plate 541, and a plurality of latch teeth 5251 at a corresponding position are fixedly connected at the bottom end of the fixed rod 542. 1 is a rack gear 543 connected with each other, a connecting plate 544 is fixedly connected between the two rack gears 543 at relative positions, sliding grooves 512 are provided on both sides of the inner top surface of the shaped frame 51, rectangular columns 545 are fixedly connected at the four corners of the top surface of the fixed plate 541, a rectangular sleeve 546 is slidably sleeved on the outer side of the rectangular column 545, a spring is fixed between the rectangular column 545 and the rectangular sleeve 546 at the corresponding position, and a slider 547 slidably connected to the sliding groove 512 at the corresponding position is fixedly connected to the top of the rectangular sleeve 546.

[0033] In this embodiment, when it is necessary to adjust the distance between the two fans 523, the staff can hold the fixed plate 541 with their hands and lift it upwards, so that the four racks 543 can be disengaged from the multiple teeth 5251 at the corresponding positions, and the two fans 523 can be moved. When the distance between the two fans 523 is adjusted, the hand is pulled out, and the fixed plate 541 returns to its original position under the elastic action of the four springs, so that the racks 543 are engaged with the multiple teeth 5251 at the corresponding positions, which can prevent the fan 523 from sliding between the two rectangular grooves 5221 at the corresponding positions.

[0034] Example 3

[0035] As Figure 7 and Figure 8 shown, in this embodiment, two symmetrical complete bevel gears 526 are fixedly connected to one end of the outer wall of the round rod. One side of the limit block 525 adjacent to one of the complete bevel gears 526 is fixedly connected with an L-shaped plate 527 that rotates through the round rod. The rotating assembly 53 includes two symmetrical racks 531 fixedly connected to the inner top surface of the C-shaped frame 51. A connecting rod 532 rotates through the top surface of the L-shaped plate 527. At the bottom end of the outer wall of the connecting rod 532, a half bevel gear 533 meshing with the two complete bevel gears 526 at the corresponding positions is fixedly connected. At the top end of the outer wall of the connecting rod 532, a spur gear 534 meshing with the rack 531 at the corresponding position is fixedly connected. A cross-shaped sliding hole 513 is formed through the top surface of the C-shaped frame 51 along its width direction. A first sliding block 535 sliding in the sliding hole 513 is fixedly connected to the top surface of the rack 531. An extension block is fixedly connected to the top end of the first sliding block 535. Screws 536 are fixedly connected to the opposite side surfaces of the two extension blocks. A threaded sleeve 537 is screwed between the two screws 536. A second rectangular hole 548 for the two connecting rods 532 to pass through and slide is formed through the top surface of the fixed plate 541.

[0036] In this embodiment, by rotating the two reciprocating lead screws 521, the moving plate 522 can be moved. Since the two connecting rods 532 pass through and slide in the second rectangular hole 548, and the connecting rods 532 rotate through the corresponding L-shaped plates 527, the moving moving plate 522 can make the fixed plate 541 follow the movement through the two connecting rods 532. During the movement of the connecting rods 532, since the two racks 531 are fixed to the C-shaped frame 51 and the spur gear 534 meshes with the rack 531 at the corresponding position, during the movement of the connecting rods 532, the spur gear 534 rotates under the meshing of the rack 531, so that the connecting rods 532 can move and rotate at the same time. Since the half bevel gear 533 meshes with the two complete bevel gears 526 at the corresponding positions, the rotating half bevel gear 533 can make the corresponding fans 523 reciprocally tilt and rotate, so that the wind generated by the fans 523 can cover the transfer paper. At the same time, before adjusting the distance between the two fans 523, first rotate the threaded sleeve 537 to make the two screws 536 approach or move away from each other, so as to adjust the distance between the two racks 531, and then adjust the distance between the two fans 523, so that the spur gear 534 can mesh with the rack 531 at the corresponding position.
